A flexible, scalable and modularly expandable solution for any FTTx application was needed, ideally providing advantages such as the intended ease of use, less downtime and lower installation costs.

Challenge: higher availability at lower cost 

GTT provides multinationals with expansive network reach and a diverse suite of cloud networking services, securely connecting them to services, applications and cloud service providers around the world. Because the company has grown through acquisitions, their tier 1 IP network consists of components from various suppliers. «I have been responsible for the Northern European infrastructure for 15 years, which up until the end of May 2018 was part of Interoute, acquired by GTT,» explains Mark Zuijdendorp, Field Engineering Manager Benelux & Nordics at GTT Communications. «In order to simplify management and reduce the inventory of products required for servicing our network, we had been searching for a better fiber closure for a number of years. R&M drew our attention to the SYNO Dome Closure in 2017. After extensive independent testing, it appeared to offer us several benefits the most important of which are lower installation and management costs and higher availability of our network connections.»

Solution: reusable SYNO Dome Closure

An important functional requirement for GTT Benelux was that the new closure had to be suitable for 12 to 432 fiber cables. Other requirements were installation time, ease of maintenance and durability. «The main benefit of R&M’s SYNO Dome Closure is the short installation time,» says Mark Zuijdendorp. A further advantage the client emphasizes is that, on average, the dome closure saves an hour and a half per connection, both for new connections and for troubleshooting. This reduces their service window, which means they are less likely to exceed customers’ SLA response time. Another advantage is its durability, as R&M’s dome closure can be easily reused thanks to the cold gel sealing. This is useful both in terms of new connections that may require modifications at a later date and for replacement work. Finally, the SYNO Dome Closure can be expanded modularly, allowing the more flexible upgrading of existing connections.

Innovation: flexible FTTx solution

The R&M SYNO Dome Closure is a high-quality connection with which we are better prepared for the future of ever faster networks.

Thanks to its reusability and modularity, R&M’s SYNO Dome Closure is a flexible solution for every FTTx application. Eight radially placed input kits support all common cable types and configurations, while different types of fiber optic cables are particularly easy to insert through the bottom. They are also easy to open and close for modifications, which gives GTT Benelux the aforementioned savings in installation and service times. The Single Circuit Management System by R&M in the SYNO Dome Closure is scalable to 1,152 connections and has a 40 mm bend radius to support the glass fibers. Furthermore, the innovative reusable cold sealing gel ensures optimum protection of all fibers and thus improved availability and performance of the fiber connections.

Practical experience: R&M project support

GTT Benelux has been working with the SYNO Dome Closure with complete satisfaction since the beginning of 2018. The use of other components also has consequences for the installation partners of infrastructure suppliers, system documentation and inventory of products. In order to prepare the first implementations, a dedicated Product Manager from R&M Headquarters in Switzerland trained the main contractor and installation partners at GTT Benelux at a central location in the Netherlands. «Thanks to the knowledge, experience and collaboration between R&M and the distributor 6X International, our transition to the new closure has been a smooth one,» concludes Zuijdendorp. «After the training all fiber optic technicians were enthusiastic about the ease of installation. The R&M SYNO Dome Closure is a high-quality connection with which we are better prepared for the future of ever faster networks.»
